Description
A/D Start
Clearing this bit to 0 stops A/D conversion, and the A/D
converter enters wait state.
Setting this bit to 1 starts A/D conversion. In single mode,
this bit is cleared to 0 automatically when A/D conversion
on the specified channel ends. In scan mode, A/D
conversion continues sequentially on the specified
channels until this bit is cleared to 0 by software, a reset,
or hardware standby mode. In addition, when the
ADSTCLR bit in ADCR is 1, the ADST bit is automatically
cleared to 0 upon completion of A/D conversion for all of
the selected channels to stop A/D conversion.
The ADST bit is automatically cleared at a different time
from that of setting the ADF bit. The ADST bit is cleared
before setting the ADF bit.
Extended Clock Selection
Sets the A/D conversion time in accord with bits CKS1
and CKS0 in ADCR and the ICKSEL bit in ADMOSEL.
For details, see section 22.3.4, A/D Control Register_0
(ADCR_0) for Unit 0. Write to the EXCKS bit at the same
time as bits CKS1 and CKS0 in ADCR.
